The Sir John Herschel Collection
The preparation of the print Calendar of the Correspondence of Sir John Herschel (Michael J. Crowe ed., David R. Dyck and James J. Kevin assoc. eds, Cambridge, England: Cambridge Univ. Press, 1998, viii + 828 pp) which was funded by the National Science Foundation, took ten years. It was accomplished by a team of seventeen professors, visiting scholars, graduate students, advanced undergraduates, and staff working at the University of Notre Dame.
The first online version of Calendar was created in 2009 by Dr Marvin Bolt and Steven Lucy, working at the Webster Institute of the Adler Planetarium, and it is that data that has now been reformatted for incorporation into Ɛpsilon.
Further information about Herschel, his correspondence, and the editorial method is available online here: http://historydb.adlerplanetarium.org/herschel/?p=intro
No texts of Herschel’s letters are currently available through Ɛpsilon.

Weather has been unsuitable for using the actinometers. Sends a small parcel of geological specimens. J. H. Lefroy is in a very good situation at Longwood.
Magnetic observatory is still not operational one year after FW's arrival. Thomas Maclear is now in 'Zwartsland' [Zwartkops?]. FW shares quarters with C. P. Smyth and William Mann. Hopes to begin observations next week at Cape Town and Simon's Bay; G. G. Lewis will make observations at Grahamstown. Problems with meteorological instruments. Proposes magnetic survey of entire colony. [JH annotation: Enquire what FW meant about measurement conversions, malfunctioning needle, and broken tube in 19 Feb. 1841 letter to Humphrey Lloyd.]
M. F. B. Dausse visited FW several times to study instruments and copy meteorological observations. Dausse urged FW to share these with D. F. J. Arago, who is concerned at delay in publishing survey results. Please notify R.S.L. that Arago's official request will arrive soon. Encloses copy of FW's 15 Apr. 1841 letter to Arago. New rain gauge. Problems with anemometer and dipping needle. Will visit Cape Agulhas with Thomas Maclear to make magnetic observations.
Has been unable to make many readings with the actinometer. Is expecting some irregular readings with the magnetometers. Survey of South Africa appears very distant. Relates recent events in Natal and with the Boers.
Is on the point of returning to the Cape and will be pleased to deliver anything to Thomas Maclear. Has borrowed three chronometers from the Admiralty for the magnetic survey. His stay was too short for him to visit JH.
Has received the two parcels of books. Regarding imperfections in the actinometer.
Outlines the recent activities connected with the magnetic survey of the Cape and comments on the progress. Gives details of difficulties under which Thomas Maclear works at the Cape Observatory.
Forwarding a letter of Thomas Maclear. Has just left the Cape. Comments on the conditions there and outlines some of the difficulties.
T. G. Taylor of the Madras Observatory has just died. Would like JH's support for William Mann for the position.
